Bug#984763: systemd: Please include configurable systemd prefixes in Debian 11's systemd (fixed upstream)

[Diego Escalante Urrelo]

Package: systemd
Version: 246.6-5
Severity: important
Tags: patch
X-Debbugs-Cc: diegoe at gnome.org

Dear Maintainer,

In systemd-247.*, the `systemd.pc` file was modified to hard-code
`/usr/lib` as the prefix of a bunch of systemd paths. This broke build
tools like `jhbuild`, that configure and install into a custom prefix
for development and testing purposes.

The above issue was fixed usptream in:
https://github.com/systemd/systemd/commit/60bce7c6d9606185114df1bdcd5ea100407688b8#diff-3dce99316f44198c53d8147020aaca9c8931b5248587c64c098fdcef8ed4da03

However the above has not been backported by upstream to v247-stable:
https://github.com/systemd/systemd-stable/blob/v247-stable/src/core/systemd.pc.in

I'm filling against Debian, and not upstream, since I don't know if
Debian plans to keep updating to the following 247.n versions, or if
247.3 will be frozen for all of Debian 11. If it's the second case, then
it would be really helpful to cherry-pick the above fix so that the
`systemd.pc` file is fully functional.

Thanks!
